PTX5000 Troubleshooting Resources Overview

To troubleshoot a PTX5000, you use the Junos OS command-line interface (CLI), LCD, alarms, devices connected to the alarm relay contacts, and LEDs on both the components and craft interface.

LEDs—When the Routing Engine detects an alarm condition, it lights the red or yellow alarm LED on the craft interface as appropriate. In addition, you can also use the component-specific LEDs on the craft interface and on the faceplate of a component to troubleshoot the PTX5000.
LCD—When a red or yellow alarm occurs, the cause of the alarm messages is displayed on the craft interface LCD. Use the CLI to display more information about the alarm.
Alarm devices connected to the alarm relay contact—When a red or yellow alarm occurs, it trips the corresponding alarm relay contact.
CLI—The CLI is the primary tool for controlling and troubleshooting hardware, Junos OS, routing protocols, and network connectivity. CLI commands display information from routing tables, information specific to routing protocols, and information about network connectivity derived from the ping and traceroute utilities. For information about using the CLI to troubleshoot the Junos OS, see the appropriate Junos OS configuration guide.
JTAC—If you need assistance during troubleshooting, you can contact the Juniper Networks Technical Assistance Center (JTAC) by using the Web or by telephone. If you encounter software problems, or problems with hardware components not discussed here, contact JTAC.

Craft Interface LEDs

The craft interface displays system status messages and allows you to troubleshoot the PTX5000. See PTX5000 Craft Interface LEDs.

Note:

The FPC LEDs are located on the FPC faceplate.

LEDs on the craft interface include:

Red and yellow alarm LEDs—One large red circular LED and one large yellow triangular LED indicate two levels of alarm conditions. You can determine the cause of the alarm condition by looking at the LCD on the craft interface.
SIB LEDs—One bicolor green and red OK indicates the status of each SIB. One green (ACT) LED indicates if the SIB is active and passing traffic. The SIB LEDs are located on the left of the craft interface, and are labeled SIB0 through SIB8.
Host subsystem LEDs—Three LEDs (one green MASTER, one green OK, and one red FAIL) indicate the status of each host subsystem. The host subsystem LEDs are located on the upper right of the craft interface, and are labeled HOST0 and HOST1.
CCG LEDs—Three LEDs (one green MASTER, one green OK, and one red FAIL) indicate the status of each host subsystem. The CCG LEDs are located on the upper left of the craft interface, and are labeled CCG0 and CCG1.
Fan tray LEDs—One bicolor green and red LED for each fan tray labeled 0, 1, and 2 that indicates the status of the fan tray.
PDU LEDs—One bicolor green and red OK LED for each PDU labeled 0 and 1, which indicates the status of the PDU.
PSM LEDs—One bicolor green and red LED for each PSM labeled 0 and, 1, 2, and 3, which indicates the status of the PSM.

Component LEDs

The following LEDs are located on various PTX5000 components and display the status of those components:

SIB LEDs—Three LEDs on each SIB faceplate—ACTIVE, OK, and FAIL—indicate the status of that SIB.

See PTX5000 Switch Interface Board LEDs.
Control Board LEDs—Three LEDs on each Control Board faceplate—ACTIVE, OK, and FAIL— indicate the status of that Control Board. Two port LEDs—HOST/ETHERNET and ACT—indicate the port speed and status.

See PTX5000 Control Board LEDs.
CCG LEDs—Three LEDs on each CCG faceplate indicate the status of that SCG. If no LEDs are lit, the CCG is not receiving power.

See PTX5000 Centralized Clock Generator LEDs.
PIC LEDs—Each port on each PIC has an LED that indicates the status of the port.

See the PTX Series Interface Module Reference.
PDU LEDs—The LEDs on each PDU faceplate indicate the status of that PDU.

See PTX5000 AC Power Distribution Unit LEDs and PTX5000 DC Power Distribution Unit LEDs.
PSM LEDs—The LEDs on each PSM faceplate indicate the status of that PSM.

See PTX5000 AC Power Supply Module LEDs and PTX5000 DC Power Supply Module LEDs.

PTX5000 Alarm Messages Overview

When the Routing Engine detects an alarm condition, it lights the red or yellow alarm LED on the craft interface as appropriate, trips the corresponding alarm relay contact, and reports the cause of the alarm in the craft interface LCD.

Look at the PDU and PSM LEDs on the craft interface.
If both PDUs fail, the system temperature might have exceeded the threshold, causing the system to shut down. If the temperature exceeds the acceptable maximum, the Control Board turns off the PDUs.

Check the temperature of components that are monitored for temperature alarms by issuing the show chassis environment monitored command. For more information about temperature alarms, see Table 6.

Verify that the status of each component is OK.

Note:

Exhaust A, Exhaust B, TLn, TQn, Ambient, Exhaust, and Junction correspond to temperature sensors located on the respective hardware component.

The output is similar to the following:

Problem

Description

The following alarms and LEDs indicate a problem with the power system during normal operations:

Table 7 lists alarms for the PDUs.
Table 8 lists abnormal LED states for the PDUs.

Solution

Verify that the source customer-site circuit breaker has the proper current rating. See PTX5000 DC Power Electrical Safety Guidelines or PTX5000 AC Power Electrical Safety Guidelines.
Verify that the power feeds are properly distributed.
- All inputs on a DC PDU in slot PDU0 must be powered by dedicated power feeds derived from feed A, and all inputs on a DC PDU in slot PDU1 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.
- The AC power cord on an AC power supply in slot PDU0 must be powered by a dedicated power feed derived from feed A, and The AC power cord on an AC power supply in slot PDU1 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.

Issue the show chassis alarms command to check for PDU alarms. See Table 7.

Check the display on the craft interface to determine the source of a yellow or red alarm). Junos OS constantly updates the screen with status information for each component.

Note:
From the rear of the chassis, the PDUs are labeled PDU1 and PDU0, from left to right.
Check the LEDs on each PDU faceplate. See Table 8.
Verify that the DC power cable or the AC power cord from the power source to the PDU is not damaged. If the insulation is cracked or broken, immediately replace the DC power cable or AC power cord.

Check the status of the PDUs by issuing the show chassis environment pdu command. The state of the PDU must be online. If the output indicates that a PSM in the PDU is present, see Troubleshooting the PTX5000 Power Supply Modules.

Troubleshooting the PTX5000 Switch Fabric

Problem
Solution

Problem

Description

The switch fabric in the PTX5000 includes the SIBs and the FPCs. A link that is in a down or error state indicates a problem with the switch fabric.

Solution

To troubleshoot the switch fabric:

Verify that all nine SIBs and all installed FPCs are online. Use the show chassis fabric summary command to check for errors.

If a SIB or FPC is Offline, see Troubleshooting the PTX5000 FPCs and Troubleshooting the PTX5000 Switch Interface Boards to correct the problem before proceeding.

Use the show chassis fabric topology command to query the state of the links between the SIBs and FPCs.

For an FPC and a SIB that are online, the Down state indicates that the link between an FPC and a SIB is powered down. The Down state for the links can also indicate that an FPC or a SIB is offline.
The Error state indicates that the link between an FPC and a SIB is not operational. The partner link may be in the Down or OK state. If the state of the link is Error, replace the FPC and SIB with a spare to determine if the fault follows the FPC or SIB. After removing an FPC or a SIB, inspect the FPC or SIB connectors for bent pins. If the FPC or SIB is faulty, return it. Before installing a spare FPC or SIB, use a flashlight to inspect the midplane for bent pins. If any pins on the midplane appear to be bent, contact JTAC immediately.

Red	`FPC fpc-number unreachable PFEs offlined`	`FPC fpc-number unreachable PFEs offlined`	FPC is not able to forward traffic due to a fabric failure.	Contact JTAC. JTAC needs to analyze the logs to see the reason for the fabric failure.
Yellow	`Power Budget: Minor alarm`	`Power Budget: No redundant power`	Redundant power is not available for one or more FPCs. If the nonredundant PSM providing power to an FPC fails, the FPC will lose service.	If any PSM is missing, add the PSM. If any PSM fails, replace the PSM.
Yellow	`FPC fpc-number SIB Link Error`	`FPC fpc-number detects link error`	An FPC detected link errors on the high speeds links between an FPC and SIB. This alarm might be caused by an error either on an FPC or on a SIB. The Packet Forwarding Engine's forwarding capacity might be affected.	Restart the SIB, and then the FPC. This might affect the traffic. If the problem persists, replace the FPC. If the problem still persists, replace the particular SIB that was associated with the link error. If you are unable to isolate the problem, contact JTAC. JTAC needs to analyze the logs to determine further action.
